Important notes about Path of Exile 2 Currency Destabilization:

Not all rooms destabilize at once
Which rooms vanish depends on their type.
This process is gradual, not a full wipe

While this method won't completely reset your temple, it's useful for removing a few poorly placed rooms over time.

Understanding Which Rooms Destabilize

Different room types behave differently when a temple run ends:

Reliquaries and Vaults of Reverence only destabilize after being complete.d
Some encounter rooms destabilize when the temple closes, but only if explicitly stated in their description.on
Core progression rooms tend to persist longer

This means that selectively clearing or skipping certain rooms can help you control which parts of the layout disappear.

Resetting the Temple by Beating Bosses

Defeating the Royal Architect

If you want a more impactful reset, your next goal should be the Royal Architect.

Defeating the Architect causes multiple rooms in your Vaal Temple to disappear, effectively rolling back much of your progress and opening up the layout for restructuring. This is often the best option if your temple is partially broken, but you can still reach the boss.

Interestingly, dying to the Royal Architect may also buy POE 2 Currency cause room destabilization, though this behavior may change in future patches.
